Abstract

The purpose is to form images in a middle of a transparent media. Accordingly, the present invention has a structure as follows. A display device including: a plate shaped display medium, having a first major surface and a second major surface, disposed on the pedestal, in which the display medium includes the liquid crystal display panel, disposed in a first transparent medium of refractive index n1, first LEDs, which supply light to the liquid crystal display panel, are disposed in the pedestal, a second transparent medium of refractive index n2 exists between the first LEDs and the liquid crystal display panel, and n2>n1.

Claims

exact text as granted — not AI-modified
What is claimed is: 
     
       1. A display device comprising:
 a plate shaped display medium, having a first major surface and a second major surface, disposed on a pedestal, 
 wherein 
 the display medium includes a liquid crystal display panel, disposed in a first transparent medium of refractive index n1, 
 first LEDs, which supply light to the liquid crystal display panel, are disposed in the pedestal, 
 a second transparent medium of refractive index n2 exists between the first LEDs and the liquid crystal display panel, and n2>n1, 
 a pole is set on the pedestal, 
 second LEDs are disposed in the pole, and 
 the second transparent medium exists between the second LED and the liquid crystal display panel. 
 
     
     
       2. A display device comprising:
 a plate shaped display medium, having a first major surface and a second major surface, disposed on a pedestal, 
 wherein 
 the display medium includes a liquid crystal display panel, disposed in a first transparent medium of refractive index n1, 
 first LEDs, which supply light to the liquid crystal display panel, are disposed in the pedestal, 
 a second transparent medium of refractive index n2 exists between the first LEDs and the liquid crystal display panel, and n2>n1, 
 an outer frame is formed to surround the display medium, 
 second LEDs are disposed in the outer frame, and 
 the second transparent medium exists between the second LEDs and the liquid crystal display panel. 
 
     
     
       3. The display device according to  claim 2 ,
 wherein the liquid crystal display device is surrounded by the first LEDs and the second LEDs in a plan view. 
 
     
     
       4. The display device according to  claim 2 ,
 wherein the liquid crystal display device is surrounded by the second transparent medium in a plan view, and 
 the second transparent medium is sandwiched by the first transparent medium. 
 
     
     
       5. A display device comprising:
 a plate shaped display medium, having a first major surface and a second major surface, disposed on a pedestal, 
 wherein 
 the display medium includes a liquid crystal display panel, disposed in a first transparent medium of refractive index n1, 
 first LEDs, which supply light to the liquid crystal display panel, are disposed in the pedestal, 
 a second transparent medium of refractive index n2 exists between the first LEDs and the liquid crystal display panel, and n2>n1, 
 a film like wiring substrate to supply signals to the liquid crystal display panel is disposed between the pedestal and the liquid crystal display device, 
 the film like wiring substrate is formed by a transparent base material of refractive index n3, n1>n3, and 
 wirings are formed on the transparent base material. 
 
     
     
       6. The display device according to  claim 5 ,
 wherein the film like wiring substrate exists in the second transparent medium. 
 
     
     
       7. The display device according to  claim 5 ,
 wherein a film of refractive index n4 is formed on a surface of the transparent wiring substrate, and 
 n4 is between n2 and n3. 
 
     
     
       8. The display device according to  claim 5 ,
 provided a refractive index of the wirings formed on the film like wiring substrate is n5, 
 a film of refractive index n6 is formed on the wirings, and 
 n6 is between n2 and n5.
